rsi: fix a double free bug in rsi_91x_deinit()

2019-09-03T13:54:48Z

`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.

rsi: Properly initialize data in rsi_sdio_ta_reset

2019-05-28T11:31:36Z

When building with -Wuninitialized, Clang warns: drivers/net/wireless/rsi/rsi_91x_sdio.c:940:43: warning: variable 'data' is uninitialized when used here [-Wuninitialized] put_unaligned_le32(TA_HOLD_THREAD_VALUE, data); ^~~~ drivers/net/wireless/rsi/rsi_91x_sdio.c:930:10: note: initialize the variable 'data' to silence this warning u8 *data; ^ = NULL 1 warning generated. Using Clang's suggestion of initializing data to NULL wouldn't work out because data will be dereferenced by put_unaligned_le32. Use kzalloc to properly initialize data, which matches a couple of other places in this driver.
